(6, -12)

Answer 1

@JMark

Answer 2

coordinates of middle point, are:
\[x _{M}=\frac{ x _{1}+x _{2} }{ 2 },y _{M}=\frac{ y _{1}+y _{2} }{ 2 }\]
where (x_1,y_1) and (x_2,y_2) are your points

Answer 3

@kittymeow101 please substitute your coordinates into formulas above

Answer 4

i really dont understand this

Answer 5

why? for example:
\[x _{M}=\frac{ 2+4 }{ 2 }=3\]
please do the same, to evaluate y_M

Answer 6

ok ill try

Answer 7

\[\frac{ 2-5 }{ 2 }=\frac{ 3 }{ 2}\]

Answer 8

im sure that wrong...

Answer 9

\[y _{M}=\frac{ -5-7 }{ 2 }=-6\]

Answer 10

oh now i get it

Answer 11

so option B. M=(3,-6)

Answer 12
